Fig. 4 is the networking diagram for the WLAN that one embodiment of the application provides.Hold as shown in figure 4, being provided with multiple AP in WLAN Device, AP container are connected to AC by Internet, one or more super thin AP are mounted under each AP container.

In the embodiment of the present application, after AP container powers on, which will initiate the foundation of the CAPWAP connection between AC Process.

Fig. 5 establishes the method flow diagram that CAPWAP is connect with AC for AP container provided by the embodiments of the present application, specific to walk It is rapid as follows:

Step 500: being arranged under AP container and super thin AP, a super thin AP in a wlan and hang under an AP container.

Wherein, each super thin AP has unique MAC Address, and each AP container has unique IP address and MAC Address.

It is hung under an AP container under one super thin AP, each AP container following can hang multiple super thin AP.

Step 501: in advance that the model of the AP container (or model+sequence number) is corresponding for every kind of AP container The corresponding each image of model (or model+sequence number) for all super thin AP that image (image) and the AP container are supported is beaten In an image packet, by image packet configuration on AC.

The index of the image packet be AP container model (or model+sequence number), i.e., according to the model of AP container (or Person's model+sequence number) the image packet can be indexed.Image generally refers to the image of operating system.

In addition, the image of a default is further comprised when factory in the non-volatile memory medium (such as Flash) of AP container Packet, the image packet include the corresponding image of model (or model+sequence number) of AP container and the institute that the AP container is supported There is the corresponding each image of model (or model+sequence number) of super thin AP.

Step 502:AP container powers on, and starts itself operating system according to the image in itself Flash, issues to AC CAPWAP join (addition) message, the message carry the information such as the IP address of itself.

It should be noted that after AP container powers on, if with obtaining the IP of AC by static or dynamic mode The IP address of location, the AC that then be used directly issues CAPWAP join message to corresponding A C；Otherwise, AP container issues broadcast CAPWAP discovery (it was found that) message, then one is selected in returning to the AC in CAPWAP discovery response message It is a, CAPWAP join message is issued to selected AC.

Wherein, the specific implementation for the IP address that AP container obtains AC by static or dynamic mode can be found in IETF 3.3 chapters of RFC 5415.

Step 503:AC receives the CAPWAP join message, returns to CAPWAP join response message to AP container.

The step 504:AP container reception CAPWAP join response message, the CAPWAP connection between AP container and AC are built It is vertical.

After CAPWAP connection between AP container and AC is established, AP container can request image, config (to match from AC Set) etc..

Step 505:AP container to AC send CAPWAP image message, the message carry the IP address of itself, model (or Person's model+sequence number) etc. information.

Step 506:AC receives the CAPWAP image message, the model (or model+sequence carried according to the message Number) corresponding image packet is found, which is carried and returns to AP container in CAPWAP image response message.

The corresponding image of model (or model+sequence number) that AP container is not only carried in the image packet, takes simultaneously The corresponding each image of model (or model+sequence number) with all super thin AP that AP container is supported.

The step 507:AP container reception CAPWAP image response message, saves the image packet in the message, sends out to AC Send CAPWAP config message.

Here, if the version of the corresponding image of model (or model+sequence number) for the AP container for including in the image packet This is different from the version of the image in the Flash of AP container, then AP container is updated in Flash with the image in the image packet Image, then restart, using image start-up operation system updated in Flash, and establish with AC CAPWAP company again It connects.

Step 508:AC receives the CAPWAP config message, returns to CAPWAP config response message to AP container, The message carries configuration information.

It should be noted that different from the CAPWAP config response message that AC is returned to Fit AP, AC is returned to AP container Radio-frequency configuration information is not carried in the CAPWAP config response message returned, and only carries wired mouthful of configuration information and general Configuration information is such as: SSID (Service Set Identifier, service set), channel number etc..

The step 509:AP container reception CAPWAP config response message, saves the configuration information in the message.

In addition, the CAPWAP connection maintenance mode between existing Fit AP and AC is identical, built between AP container and AC After vertical CAPWAP connection, can by the maintenance heartbeat of CAPWAP Echo (echo) message, when a side in default heartbeat duration not The CAPWAP Echo message that other side sends is received, then disconnects CAPWAP connection.

After super thin AP is powered on, control and data channel are established with AP container.

Fig. 6 is the method flow diagram that super thin AP provided by the embodiments of the present application and AP container establish control and data channel, The specific steps of which are as follows:

Step 600: being arranged under AP container and super thin AP, a super thin AP in a wlan and hang under an AP container.

Each super thin AP has unique MAC Address, and each AP container has unique IP address and MAC Address.

Step 601: when super thin AP is powered on, issuing broadcast probe messages, which carries the MAC Address and model of itself.

Broadcast probe messages can also carry the information such as the sequence number of super thin AP, VLAN ID.

Step 602: any AP container reception is to the broadcast probe messages, if finding itself to support the model of the super thin AP (or model+sequence number) then replys a response detected message to the super thin AP, and the message is with carrying the MAC of this AP container Location.

Response detected message can also carry the information such as access capability, present load, the VLAN ID of AP container.

Step 603: super thin AP receives the response detected message that each AP container returns, select an AP container as oneself Work AP container, sends image request message to the work AP container of oneself, which carries the MAC Address of itself, type Information such as number (or model+sequence numbers).

Specifically, super thin AP can select an AP container as the work AP of oneself according to the load etc. of each AP container Container.

Step 604: the work AP container reception of the super thin AP image request message, the model carried according to the message (or Person's model+sequence number), corresponding image is found in the image packet saved in the Flash of itself, which is carried Super thin AP is sent in image response message.

Specifically, AP container is when receiving the image request message that super thin AP is sent, according in image request message Found in the image packet that model (or model+sequence number) saves in the flash of itself corresponding image return to it is super Thin AP.

Step 605: super thin AP receives the image response message that the work AP container of oneself returns, and is carried according to the message Image, formally start itself operating system, establish control and data channel with oneself work AP container.

Step 606: after the control and the success of data Path Setup between super thin AP and the work AP container of oneself, the work AP container creates corresponding virtual AP process at itself for the super thin AP.

As it can be seen that AP container can be for the super thin AP for each establishing control and data channel with oneself, in itself creation one Virtual AP process.

AP container and super thin AP establish control and data channel, and AP container itself is creating virtual AP for super thin AP After process, which, which can represent the super thin AP and AC, establishes CAPWAP and is connected to.

Fig. 7 is that the virtual AP process on AP container provided by the embodiments of the present application establishes the method stream that CAPWAP is connect with AC Cheng Tu, the specific steps of which are as follows:

Virtual AP process on step 701:AP container issues CAPWAP join message, the source IP which carries to AC Address is the IP address of AP container, and source port number is the UDP port number of the virtual AP process.

It should be noted that if virtual AP process has obtained the IP address of AC by static or dynamic mode, Then be used directly the AC IP address to corresponding A C issue CAPWAP join message；Otherwise, virtual AP process issues broadcast Then CAPWAP discovery message selects one, to institute in returning to the AC in CAPWAP discovery response message The AC of selection issues CAPWAP join message.Preferably, the AC's that virtual AP process can be saved directly using AP container itself IP address.

Wherein, the specific implementation for the IP address that virtual AP process obtains AC by static or dynamic mode can be found in 3.3 chapters of IETF RFC 5415.

Step 702:AC receives the CAPWAP Join message, returns to CAPWAP join response report to the virtual AP process Text.

Step 703: virtual AP process receives the CAPWAP join response message, and the CAPWAP between AC connect foundation.

In step 702~703, DTLS (Datagram Transport can also be established between virtual AP process and AC Layer Security, data packet Transport Layer Security) encryption connection, to guarantee the safety of CAPWAP connection.

After CAPWAP connection between virtual AP process and AC is established, virtual AP process can request config from AC (configuration).

Step 704: virtual AP process sends CAPWAP Config (configuration) message to AC.

Step 705:AC receives the CAPWAP Config message, returns to CAPWAP config response report to virtual AP process Text, the message carry the configuration informations such as radio-frequency configuration, pass-through mode configuration.

It is identical that radio-frequency configuration information with existing AC is handed down to the radio-frequency configuration information of Fit AP, comprising: SSID, transmits and receive telegrams Rate, the power etc. of text.

Pass-through mode configuration includes: the VLAN ID for supporting to concentrate forwarding, or/and supports the VLAN ID locally forwarded.

In addition, CAPWAP config response message can also carry the configuration informations such as speed-limiting messages, bandwidth restricted information.

Step 706: virtual AP process receives the CAPWAP response message, saves the configuration information of message carrying, and will Radio-frequency configuration information is handed down to corresponding super thin AP by control channel.

In addition, AP container periodically will report the status information of itself, configuration to update letter to AC in the embodiment of the present application Breath, Event (event) information etc.；Meanwhile each virtual AP process also will periodically report status information, the configuration of itself to AC More new information, Event (event) information etc..

Step 707: super thin AP receives and saves the radio-frequency configuration information that virtual AP process issues.

Fig. 8 is under concentration pass-through mode provided by the embodiments of the present application, and wireless site (STA, station) is sent out to server Deliver newspaper text method flow diagram, the specific steps of which are as follows:

Step 801:STA sends 802.11 message of IEEE to super thin AP by Wi-Fi network interface card.

Step 802: radio (radio) radio frequency chip of super thin AP receives the message, which is sent to upper layer mould Block issues interface module after the format of the message is converted to IEEE 802.3 by upper layer module, and interface module leads to the message It crosses data channel and is sent to AP container, which carries the radio-frequency information of the message.

The radio-frequency information of message includes: the rate of message, channel, RSSI (Received Signal Strength Indication, received signal strength indicator), SNR (Signal-Noise Ratio, signal-to-noise ratio) bottom the information such as makes an uproar.

Step 803:AP container extracts the message from data channel, by the message distribute to corresponding virtual AP into Journey.

Data channel is one-to-one with virtual AP process.In step 206, the data between AP container and super thin AP are logical After road is successfully established and creates corresponding virtual AP process for the super thin AP, AP container can save data channel ID and virtual AP The corresponding relationship of process ID, in this way, in this step 403, AP container can according to message from the ID of data channel find Corresponding virtual AP process ID.

Step 804: virtual AP process receives the message, and the forwarding side of the message is determined according to the VLAN ID that message carries Formula is to concentrate forwarding, then the message is encapsulated in CAPWAP tunnel and is sent to AC.

Step 805:AC extracts the message from CAPWAP tunnel, carries out two layers or three layers forward process of standard to the message Afterwards, it is forwarded in cable network and send to Internet, route to Server eventually by Internet.

AC can make some complicated business processing during carrying out two layers of standard or three layers of forward process as needed, such as: QoS, DPI, 802.1X or web authentication etc., specific complicated business processing method belong to mature technology, and details are not described herein.

Fig. 9 is under concentration pass-through mode provided by the embodiments of the present application, and Server sends the method flow of message to STA Figure, the specific steps of which are as follows:

The message that step 901:Server is sent to STA is routed by Internet, reaches AC.

After step 902:AC makees two layers or three layers forward process of standard to the message, message is encapsulated in CAPWAP tunnel It is sent to AP container.

AC can make some complicated business processing during carrying out two layers of standard or three layers of forward process as needed, such as: QoS, DPI, 802.1X or Portal certification etc., specific complicated business processing method belongs to mature technology, and details are not described herein.

Step 903:AP container finds corresponding virtual AP process according to the destination slogan of message, which is sent Give the virtual AP process.

When virtual AP process is established CAPWAP with AC and connect, the UDP SOCKET of TCP/IP will use, at this point, TCP/IP association Discussing stack can be automatically using a UDP source port number corresponding with the virtual AP process, and AP container records the virtual AP process and this The incidence relation of UDP source port, in this step, for AP container according to the incidence relation, the destination slogan for finding message is corresponding Virtual AP process.

Step 904: after virtual AP process receives message, CAPWAP decapsulation is carried out to the message, obtains original message, it will The original message issues corresponding super thin AP by data channel.

Step 905: super thin AP extracts the message from data channel, according to the radio-frequency configuration information of itself, to the report Text executes radio frequency operation, and message is then sent to Radio radio frequency chip, by Radio radio frequency chip by eating dishes without rice or wine to be sent to STA.

Here, if the format for the message that super thin AP is extracted is IEEE 802.3, the upper layer module of super thin AP also needs should The format of message is converted into IEEE 802.11, then executes radio frequency operation to message again.

Wherein, radio frequency operation message executed, such as: rate and power, AMPDU (Aggregation are selected for message MAC Protocol Data Unit, polymerization media access control protocol data unit) processing etc..

From the embodiment of the present application it can be seen that

CAPWAP client need not be realized compared to more traditional Fat AP and Fit AP, super thin AP, it is not necessary to realize complexity Service processing function, it is only responsible for most basic radio frequency part function, such as: less radio-frequency packet sending and receiving, radio frequency control (speed Rate, power), AMPDU processing etc..Therefore, the hardware of super thin AP is also able to achieve most simplified, and volume can also be made very small.

Super thin AP can establish CAPWAP with AC and connect, so that AC is in own indirectly with the help of AP container Apparently, super thin AP is just as a standard AP for angle.And the complicated business for needing to operate on standard AP originally, then by " AP container " On behalf of operation.According to the actual situation, one " AP container " can manage multiple super thin AP, and the super thin AP of management is more, then AP holds The cost of device itself is just shared by a large amount of super thin AP, is totally got off, the cost of the super thin AP+AP container of identical quantity, Shi Bi great The standard AP of big quantity identical lower than deployment.Therefore, both the virtual AP unit on AP container and super thin AP add up, and are externally in A complete standard AP is showed.That is: super thin AP itself does not provide complete business function, but it combines with AP container, Complete radio function, including control plane business function and data surface forwarding capability can be provided for user.

For example, certain mininet had the super thin AP of+20, an AP container originally, fat mode networking is used.Later business expands, and needs to increase Add an AP container and 20 super thin AP, it is possible to directly connect two AP containers, two AP containers are separately operable Fat mode and thin mode (the embedded AC module of an AP container is opened, and the embedded AC module of another AP container is closed).In this way, Two AP containers can manage 40 super thin AP, and for a user, this 40 super thin AP only need the AP container in fat mode Upper configuration, network configuration will not change, and business is not lost.AC mould if network further expansion, built in AP container The performance of block is unable to satisfy requirement, then can increase a dedicated AC, simultaneously closes off the AC module of all AP containers, in this way, Just constitute AC+AP container (thin mode)+super thin AP framework.Therefore, this model has good scalability.

The advantageous effects of the embodiment of the present application are as follows:

One) super thin AP is more concerned about radio frequency itself, is no longer influenced by various complicated business, keeps super thin AP itself most simplified. Due to there is the presence of AP container, so not lost traffic characteristic.

Two) an AP container can manage multiple super thin AP, make the average price of super thin AP compared to more traditional Fit AP Or Fat AP is substantially reduced.

Three) super thin AP network is easy to extend, and is suitable for the wireless network of random scale (large, medium and small).
